LIAN LI has released official notices addressing two separate issues affecting recent products, providing guidance and support options for affected users. The announcements cover a USB connectivity and software functionality issue with the HydroShift II LCD-S liquid cooler, as well as aesthetic concerns surrounding the white cables included with the SX Platinum Series power supplies.
The company has outlined clear steps to resolve the HydroShift II LCD-S issue locally, while also offering replacement components for SX Platinum PSU owners who are dissatisfied with the current cable colour. LIAN LI has reiterated its commitment to post-launch support and encouraged users to contact its support team if further assistance is required.

HydroShift II LCD-S – Follow-Up Investigation and Design Update
LIAN LI has provided a follow-up update after completing further investigation into the HydroShift II LCD-S issue, citing community feedback as instrumental in identifying the underlying cause.
The company determined that, in some systems, motherboard backplate bending can cause the CPU to sit lower than intended. This can lead to the pump cap and integrated LCD sitting lower while the mounting bracket remains level, resulting in internal interference within the LCD cap housing. In such cases, the pogo pins may fail to maintain proper contact, causing the LCD not to power on and the USB connection to be incorrectly detected.
LIAN LI notes that the issue is not universal and depends on individual motherboard conditions, particularly the presence of backplate bending. To resolve this, the company has implemented a design update that adds a small cutout to the inner housing of the LCD cap, eliminating potential interference and ensuring consistent pogo-pin contact.
Who Is Affected
You may be affected if:
• The LCD fails to power on and remains black
• Device manager does not pick up the LCD as a USB device

SX Platinum Series PSU – Important Notice
Following the release of the SX Platinum Series PSU, we received feedback from users regarding the white cable color appearing slightly “purple.” After further review, we agree that the current white cables do carry a noticeable purple hue, which may not be visually ideal for certain PC build aesthetics.
For users who prefer a cleaner and more unified look, we’re happy to provide a replacement set of pure white cables to replace the existing ones and better complement their PC builds. To request for replacement cables, please submit a request through our Support Request Form. Our support team will assist you as soon as possible.

Late last year, LIAN LI also issued an advisory regarding the HydroShift II LCD-S 360 and an AMD bracket tolerance issue. Taken together with the latest announcements, it highlights LIAN LI’s proactive approach to post-launch support, with the company moving quickly to acknowledge user feedback and provide clear solutions or free replacement parts where necessary.
